Agreed - anyone using the "helpful" automagic stuff like vCentre for something like an RR is crazy. We've had issues with it exploding and the VMs being unmanageable.
OTOH a standalone hypervisor with no external dependencies can be pretty much bulletproof; our DNS and DHCP servers run on KVM boxes, and they're rock solid.
One advantage is reboot times - modern servers take an age to POST, but a KVM guest can reboot in under 30 seconds.
